Claims11
In a nipple for feeding liquids to a domesticated mammal, the nipple comprising an elastic molded body and having:
- a nipple tube having a distal end and a proximate end, a length between the distal end and the proximate end and a wall with a thickness that are suitable for suckling by the mammal, and having proximate its distal end a self-sealing aperture through which liquid flows from inside the nipple tube into the mammal in response to suckling by the mammal,
- a traverse wall having an inner perimeter and an outer perimeter and having an external face and an internal face, the external face being on the side of the nipple not exposed to liquid feed and the internal face being on the side of the nipple exposed to liquid feed when the nipple is used,
- a vent located between the inner perimeter and the outer perimeter of the traverse wall and having a check valve at the end of the vent, and
- a means for attaching the nipple to a container for liquid feed for the mammal, the improvement comprising an intervention member circumferentially spaced about the check valve to protect the check valve from contact with the container.
